A conventional tractor is what much of the world outside of North America refers to as a "bonneted" or "hooded" tractor. It has a hood which extends out in front of the cab. This is in opposition to a COE (cab-over-engine) tractor, where there is no hood.
This varies by the type of tractor and trailer. The standard conventional tractor ( conventional is a tractor with a sleeper berth) and trailer length is approx 72 feet from end to end but can vary from as short as 40 feet to as long as 130+ feet.

A 'conventional' tractor is what is known to the rest of the world as either a 'bonneted' or sometimes 'Arctic' tractor. It simply means that the hood and engine compartment protrude in front of the cab, as opposed to a cab-over-engine tractor, where the engine compartment sits underneath the cab. Currently, conventional tractors are all that's available new on the North American market - the last company to manufacture and market a cabover in North America was Freightliner with the Argosy, which has been discontinued for the US market, but is still manufactured for the South American, Australian, New Zealand, and southern African markets.
